thermal decomposition of ammonium perchlorate

The reaction mechanism proposed for the catalysed decomposition involves the formation of the free radicals NH4 and ClO4, decomposition of the radicals to NH3 and chlorine oxides, and subsequent oxidation of NH3. The heat effect of decomposition reaction of solid NH4ClO3to oxygen, gaseous water, and HCl (or chlorine) averages 42.5-49 kcal/mole or 419-482 cal/g depending on product composition. • … Furthermore, the catalytic effect of the obtained samples on the thermal decomposition of ammonium perchlorate (AP) was examined by thermal gravimetric analysis (TGA). X-ray diffraction (XRD), X-ray energy-dispersive spectrometry (EDS) and X-ray photoelectron spectros-copy (XPS) analyses showed that the characteristic peaks of CuO/ PbO NMOs were almost the superposition of nano CuO and nano PbO, while few new weak … This review represents an attempt to summarize literature data on thermal decomposition of ammonium perchlorate. The mechanism of thermal decomposition and various factors which influence on the thermal decomposition of ammonium perchlorate are discussed. Search for more papers by this author. Adding 10% of NGO to AP decreases the decomposition temperature by 106 °C and increases the … The catalytic effect of the NGO for the thermal decomposition of ammonium perchlorate (AP) was investigated by differential scanning calorimetry (DSC). The most striking of these is that at low temperatures it decomposes only to the extent of about 20 to 30 %, leaving a residue which is chemically identical with the original salt. The products of decomposition were identified and the yield of each was established. For reproduction of material from NJC: Reproduced from Ref.

Variations in lattice configuration of AP change … Herein, a classical catalytic mechanism based on the surface lattice oxygen was proposed to reveal AP decomposition promoted by ZnO nanosheets. Nanoparticles of Transition Metals as Accelerants in the Thermal Decomposition of Ammonium Perchlorate, Part 62. Energetic additives can effectively increase the heat release of ammonium perchlorate (AP) decomposition to prevent nonenergetic additives from decreasing the energy density of composite solid propellants. XX with permission from the Centre National de la Recherche Scientifique (CNRS) and The Royal Society of Chemistry. As an energetic accelerator for thermal decomposition of ammonium perchlorate (AP) and ammonium nitrate (AN), 10% nano TAGN blended with AP and AN, and samples “[90% AP + 10% (nano TAGN)]” and “[90% AN + 10% (nano TAGN)]” were obtained, respectively. https://doi.org/10.1016/j.tca.2005.11.038. (2013). Thermal decomposition of ammonium perchlorate. Field emission scanning electron microscopy, differential scanning calorimetry and thermogravimetry analysis techniques were used to evaluate the coating quality and thermal … In addition, 1 was explored as combustion promoter to accelerate the thermal decompositions of ammonium perchlorate (AP) by differential scanning calorimetry. The mechanism of thermal decomposition and various factors which influence on the thermal decomposition of ammonium perchlorate are discussed. Production. Good recovery of N and Cl was achieved. Thermal Decomposition of Ammonium Perchlorate containing a polymeric additive Thermal Decomposition of Ammonium Perchlorate containing a polymeric additive Thomas, T. J.; Nandi, U.
